Functional outcome of primary cemented total hip arthroplasty following displaced fracture neck of femur in elderly patients

Abstract

Background: Displaced femoral neck fracture (FNF) is one of the most common injury in the elderly patients. Effective surgical treatment is crucial to restore normal functioning hip and mobilize as early as possible. The aims of this study were to assess functional outcome after primary cemented total hip arthroplasty (THA) due displaced FNF in elderly patients by modified Harris Hip Score (HHS) and report postoperative complications. Methods: This prospective observational study included 60 patients above 60 years diagnosed with displaced FNF from January 2023 to December 2024 at National Institute of Traumatology and Orthopaedic Rehabilitation (NITOR) by convenient sampling technique. All patients underwent cemented THA through lateral (Hardinge) approach. The patients were followed up at 3rd week, at 6th week, at 3rd month and 6 monthly interval for 2 years. In each postoperative follow-up, modified HHS was done and complications were noted. Results: The mean age of the patients was 69.5 years; 37 (62%) were female and 23 (38%) were male. Left side was affected in 65% patients and fall accounted for majority (70%) cases. Hypertension (32%) and diabetes mellitus (20%) were two most common comorbidity. Five percent patient had operated limb shortening and 3.3% had superficial wound infection. Modified HHS on final follow-up showed excellent 35%, good 56.7% and fair 8.3%. Satisfactory result was obtained in 92% and unsatisfactory in 8% of the patients. Conclusion: Surgical treatment with cemented THR provided improved functional status of the patients in more than 90% cases with minimal postoperative complications.
